Engine IDLE State Warnings:
Engine IDLE state is:- DC circuit breaker on, generator not running
In the IDLE state only
Ambient Air, Temperature Low
and
.MAP
Sensor Possible Fault
are logged. If the fault persists
after the generator is started, the CRANK state and RUN state warnings and shutdowns
will
apply. There are NO
shutdowns in the IDLE state, only warnings. Shutdowns can occur in both the CRANK an.d RUN states.·
